The topic of “hair loss” remains one of the most researched medical topics by people. According to Internet search engine statistics. at the same time; Many medical facts about the causes of this condition and how to address it therapeutically are still not scientifically clear to many, especially the distinction between cases of “hair loss” and cases of “hair loss.”
Facts about hair and hair loss
Here are the following facts about hair and hair loss mechanisms:
1- Hair begins to appear on the skin at a very early stage in the fetus’s life, particularly when it is two months old. The first areas where hair appears in the fetus are: Regardless of gender, these are the eyebrows, upper lip and chin area. Then, when the fetus reaches the fourth month of life, hair begins to appear on the skin of the rest of the body. When hair is healthy in structure and strength, one hair can bear the weight of 100 grams. That is, all the hair on the scalp can withstand a weight of more than two tons. That’s the weight of two African elephants.
Hair is the second fastest growing tissue in the human body, after bone marrow tissue. Hair grows about an inch every month. There are 14 different mineral elements within the components of hair. Most of them are found in very small quantities and one of them is the metal gold. The main elements, in order of greatest presence in the components of a single hair, are: carbon, oxygen, nitrogen, hydrogen and sulphur.
2- From an anatomical point of view; The hair is originally a continuously growing protein appendage, composed of 3 layers: a hard outer cortex, a less rigid central cortex and then inside is the nucleus of the hair. The root of the hair is located under the skin in a sac called a follicle.
Among the components of the hair root is the “hair papilla”, responsible for producing the hair shaft that emerges from the skin. The growth of hair from the “hair papilla” goes through different phases: the first is the growth phase, in which hair production continues for about 5 years, then comes the rest and stagnation phase, which can last about 3 months, during which the growth of the hair shaft stops, and then comes the shedding phase, which separates. The hair is on the body.
Then the hair follicle begins to produce another hair that goes through these three phases. 90% of the hair on your scalp is in the growing phase and 10% is in the resting and stagnant phase. Each hair in the human body has its own nerve, its own blood supply and its own muscle. Hair is a storehouse of health information about a person, and analysis of hair components can determine the minerals and vitamins in the body and the medications a person is taking. However, there are no clear differences between female and male hair.
Hair loss
3- According to the results of global statistics, the global market size for hair loss treatment has reached approximately $53 billion in 2022. That is, in terms of sales of hair loss products and treatments. Over the past five years, this market has grown at a rate of 7% per year. Based on market expectations of future annual growth, the hair loss management market will be worth more than $88 billion in 2030. Men predominate in the number of people seeking hair loss products and treatments; By 65%. If only the “hair transplant” sector is taken into account, demand among men is 85% higher.
The three countries with the highest global rates of male hair loss (around 44%) are all located in Western Europe: Spain, Italy and France.
4- Approximately 85% of men and 33% of women will experience varying degrees of hair loss at some point. This problem is more common than some people think. “Male pattern baldness (or androgenetic alopecia)” accounts for approximately 95% of cases of hair loss in men. Over 65% of American men experience hair loss to varying degrees by the age of thirty-five.
By age 50, approximately 85% of men will show very visible signs of hair loss; That is, “thinning hair”. Male pattern baldness can affect men of all ages. Approximately 25% of men who suffer from hair loss begin this process before they reach the age of twenty-one. Genetics is the most important cause of hair loss. Male pattern baldness affects approximately 95% of all men who experience hair loss. Other causes can be diet, stress, lifestyle and illness.
5- In general; 40% of women who suffer from noticeable hair loss suffer from marital problems due to hair loss. Around 64% of them say they face problems related to their professional life. More than half of women may suffer from hair loss in the post-menopausal period.
A recent study indicates that more than 50% of women suffer from hair loss after reaching the age of fifty. The severity of hair loss varies depending on various factors. Women who live stressful lives are 11 times more likely to suffer from hair loss. While it’s unclear how stress can prevent the growth of hair follicles, researchers have observed such a connection. Several studies are underway to find out how stress can affect tissue regeneration.
“hair loss”
6- It is considered acceptable to “shed” between 50 and 100 hairs a day. But “hair loss” is diagnosed if a person loses more than 100 hairs a day. But there’s a big difference between “hair loss” and “hair loss,” as the American Academy of Dermatology (AAD) warns. “If you notice there’s more hair than usual on your pillow or brush, you may worry that you’re experiencing hair loss,” she says. It’s actually possible that he’s losing more hair than usual. Yes, there is a difference. While hair loss occurs when something prevents hair growth. Dermatologists can distinguish between (hair loss) and (hair loss).”
She adds: “If you’re worried about the amount of hair shedding, there’s no need to suffer in silence. You can turn to a dermatologist for help. These doctors specialize in diagnosing and treating skin, hair, and nails. A dermatologist will be able to tell you if you suffer from (hair loss) or (excessive hair loss); Some people have both. A dermatologist can also find the cause or causes and tell you what to expect. Effective treatment options are available for many types of hair loss. Previous treatment begins; “The prognosis was better.”
7- The American Academy of Dermatology (AAD) states: “Excessive hair loss is common in people who have been exposed to any of the following stressors:
– When you lose 20 pounds (about 9 kilograms) or more.
– Women giving birth.
– The woman stops taking the contraceptive pill.
– Exposure to a lot of stress (taking care of a sick loved one, divorce or job loss).
– Suffers from high fever.
– Undergoing surgery.
– Recovery from an illness; Especially if it is a high temperature.
Most people notice excessive hair loss a few months after the stressful event. For example; A new mother may notice excessive hair loss about two months after giving birth. The loss usually reaches its peak about 4 months after birth. This loss is natural and temporary.
As your body adapts, the excessive loss stops. Within 6-9 months the hair tends to regain its natural density. However, if stress persists, hair loss can continue for a long time. “People who are constantly exposed to a lot of stress may suffer from excessive long-term hair loss.”
Common causes of hair loss
8- The most common causes of “hair loss” (not “hair loss”) include:
– Hereditary hair loss.
– The immune system overreacts.
– Taking certain medications and treatments.
– Hairstyles that pull your hair.
– Aggressive hair care products.
– “Psychological compulsion” to tear out hair.
The American Academy of Dermatology states: “If you suffer from hair loss, your hair will not grow until the cause is gone. For example; People who undergo chemotherapy or radiation therapy often lose a lot of hair. When treatment stops; Their hair tends to grow back. But many people with hereditary hair loss continue to lose hair without treatment. Women who inherit genetic genes for hair loss may notice gradual hair loss. While men who suffer from hereditary hair loss tend to have a receding hairline or a bald patch starting in the center of the scalp.”
9- Hair loss occurs in many different ways, depending on the type of reason that led to the hair loss: it can be genetic, or due to hormonal changes, medical conditions, or a natural part of the symptoms of aging. It’s true that anyone can suffer from hair loss, but it is more common among men. Baldness usually refers to excessive hair loss from the scalp. Hereditary hair loss is the most common cause of baldness. People differ here; Some people may choose to abandon hair loss without hiding it, while others address baldness by hiding it or reducing the area, either with modified haircuts or by wearing a wig. They also differ in their therapeutic relationships with it. Some leave it untreated, while others explore and use all available treatments to prevent further hair loss or restore hair growth. But the basics remain to talk to a medical professional to research the type of hair loss, the cause of the hair loss and the appropriate treatment options, before starting treatment.
85% of men and 33% of women experience varying degrees of hair loss at some point.
10- Dermatologists at the Mayo Clinic say: “Indicators and symptoms of hair loss include the following:
– Gradual thinning of hair on the top of the head: This type is the most common type of hair loss. It affects people as they age. In men, hair often begins to recede at the hairline on the forehead. As for women; They are usually exposed to a widening of hair spacing. A common pattern of hair loss among older women is receding hairline (frontal fibrous alopecia).
– Circular or irregular bald spots: Some people lose hair in the form of circular or irregular bald spots on the scalp, beard or eyebrows. You may feel itchy or sore skin before hair loss.
– Sudden hair loss: Exposure to physical or emotional trauma can cause hair loss. A strand of hair may fall out when you comb it, wash it, or even after gently pulling it. This type of loss usually causes overall thinning of hair, but it is also temporary.
– Full body hair loss: Some medical problems and treatments, such as chemotherapy for cancer, can cause full body hair loss. This hair grows back.
– The spread of scaly patches on the scalp: This is an indicator of ringworm infection. This spread may be accompanied by hair breakage, redness, swelling, and sometimes oozing.
